Abstract
A solid resinous product useful for coatings, adhesives and molding materials which is obtained by polymerizing a by-product tar produced as by-product in manufacturing resorcinol or resorcinol and hydroquinone via hydroperoxide of m-diisopropylbenzene or of a combination of m- and p-diisorpopylbenzenes and containing m-substituted phenolic constituents or a combination of m- and p-substituted phenolic constituents as major constituents.
Claims3
A solid resinous product obtained by polymerizing at a temperature of 20.degree. to 240.degree. C. in the presence or absence of a solvent and in the presence or absence of a polymerization initiator a material consisting essentially of a by-product tar which is produced as by-product in manufacturing resorcinol or resorcinol and hydroquinone via hydroperoxide of m-diisopropylbenzene or of a combination of m- and p-diisopropylbenzenes and which contains m-substituted phenolic constituents or a combination of m- and p-substituted phenolic constituents as major constituents.
